ViewBoard Network Requirements

Introduction

This guide will introduce the network requirements for ViewBoard’s preloaded software and help IT administrators setup ViewBoard® products within their IT infrastructure.

NOTE:

• Please ensure the wireless infrastructure supports broadcast service and it is turned ON.
• For a more stable connection, it is recommended to have any ViewBoard® connected via LAN by Ethernet cable, and client devices on a 5 GHz Wi-Fi band.

Air Class

Display quiz questions on a ViewBoard® and allow up to 30 mobile users to submit answers remotely. Whether administrating single or multiple-choice questions, the ViewBoard® will record the results of each device being used.

Network Information

• PC (Windows/Mac/Chromebook) and tablet/mobile (iOS/Android) devices, as well as the ViewBoard®, need to be connected to the same network subnet.
• Port: TCP 8080

AirPlay Service

NOTE: Please ensure that mDNS is enabled on the network/access point/wireless controller (if applicable).

Network Information

• Ports:

TCP 51040, 51030, 51020 & 51010

UDP 5353 (mDNS to broadcast Airplay)

UDP random port with a range of 52000~53000 (Transfer audio; assigned by AirPlay protocol)

How to Verify AirPlay is Broadcasting

1. Ensure that your iOS device and the ViewBoard® are connected to the same subnet network.
2. Open the Control Center and select AirPlay Mirroring on the iOS device (e.g., iPhone/iPad).
3. Find a device prefixed with “Cast-xxxx”.
4. If “Cast-xxxx” is showing then this confirms that vCast is broadcasting AirPlay services.
5. Click on the broadcasted “Cast-xxxx” device to mirror your iOS device to the ViewBoard®.

Chromecast Service

ViewBoard® Cast software supports native Chromecast screen sharing via the Chrome browser casting with the Chromecast feature enabled.

NOTE: Please ensure that mDNS is enabled on the network/access point/wireless controller (if applicable).

Network Information

• Ports:

TCP 8008 & 8009

UDP 5353 (mDNS to broadcast CCast)

How to Verify Chromecast is Broadcasting:

1. Ensure that your Chromebook and ViewBoard® are connected to the same subnet network.
2. Bandwidth: At least 2~5 Mbps per user in a typical deployment. Latency should be less than 100 ms when pinging Google’s public DNS server at 8.8.8.8; for HD video streaming > 5 Mbps is required.
3. Access points:

For small deployments of under 30 devices, consumer-grade networking equipment is sufficient.

For deployments greater than 30 devices or involving multiple rooms, enterprise-grade, centrally managed networking equipment is recommended.

NOTE:

• It is recommended to use Wi-Fi 802.11n 5 GHz.
• Please refer to a 5 GHz channel guide for a table on non-DFS channels in your country. In the USA, those channels are 36~48 and 149~165.

Display Service

myViewBoard Display allows users to mirror their desktop wirelessly to supported Interactive Flat Panels (IFP) and Wireless Presentation Displays (WPD).

myViewBoard Display comes pre-installed on select ViewBoard® hardware, but can also be installed manually on any IFP or WPD that runs Android 6 or higher.

Once myViewBoard Display is installed on an IFP or WPD, users will only need to use a compatible browser to start mirroring their device screen to the host.

Network Information

• Ports:

TCP Port 443 (HTTPS): outbound

UDP and TCP port 3478 bidirectional to the WebRTC servers

UDP Ports 50,000 – 65,535 (RTP/sRTP/RTCP) bidirectional to the WebRTC servers (These ports are optional; if blocked, media will be proxied using TURN on port 3478.)

Manager Service

myViewBoard Manager is a tool for Entity Administrators to remotely manage multiple installations of ViewSonic visual solution devices such as a ViewBoard®.

To access, select the Entity Management tile, then All Devices on the side panel.

NOTE: This option is only available for users signed in using an Entity Administrator account. To learn more, visit: https://myviewboard.com/kb/manager.

Miracast Service

Miracast helps you wirelessly stream content from Windows and Android devices to an Interactive Flat Panel (IFP) or Wireless Presentation Display (WPD).

NOTE: Please ensure that mDNS is enabled on the network/access point/wireless controller (if applicable).

Network Information

Ports:

• TCP Port 7236 : Wi-Fi direct control port used to establish and manage sessions between the source device and ViewBoard.
• UDP port 21200 for RTP packets and UDP port 21201 for RTCP packets.
• UDP 5353 : This port is used for multicast DNS (mDNS) broadcast to the local subnet.
• IP address(s): IPv4 address: 192.168.49.0, Subnet mask: 255.255.255.

Over-the-Air (OTA) Service

A ViewBoard® will automatically search for firmware updates whenever connected to the Internet.

Network Information

• Server FQDN Name: ifp-ota.s3-accelerate.amazonaws.com, www.viewsonicglobal.com
• Server Port: TCP443

vCast & vCastSender Service

Working with ViewBoard® Cast software, the vCastReceiver app, will allow the ViewBoard® to receive vCastSender laptop screens (Windows/Mac/Chrome) and mobile (iOS/Android) users’ screens, photos, videos, annotations, and camera(s).

Network Information

• ViewBoard® Cast software, laptops, and mobile devices can connect to both the same subnet and across the subnet network.
• Please enter the on-screen PIN-code to connect to the ViewBoard.

• Ports:

• TCP 56789, 25123, 8121 & 8000 (Controlling message port & client device audio transfer)
